Preparation method, distributed winding motor stator, distributed winding motor and compressor

Abstract

The invention provides a preparation method, a distributed winding motor stator, a distributed winding motor and a compressor. The preparation method includes: disposing an insulation accommodating structure having a receiving groove at the end portion of a first-end winding of a stator winding; fixing the winding lead of the stator winding in the insulation accommodating structure; arranging a shorting connector in the receiving groove in the insulation accommodating structure and shorting the shorting connector and the winding lead; assembling an external lead to the shorting connector so that the external lead and the winding lead are shorted. The method can achieve automation and semi-automation of the motor lead-out wire process, thereby remarkably improving the production efficiency and reducing the labor cost effectively so as to improve the market competitiveness of the product.

Description

technical field [0001] The invention relates to the field of motors, in particular to a preparation method of a stator of a distributed coil motor, a stator of a distributed coil motor, a distributed coil motor and a compressor. Background technique [0002] In the related art, the manufacturing process of the traditional distributed winding motor usually includes the following production processes: placing slot insulation in the stator core slot, offline in the stator slot (including embedded and wave winding type off-line process), placing slot wedges and Phase insulation, initial forming of winding ends, motor connection and outgoing wires (lead wire cutting, lead wire stripping, lead wire twisting, lead wire short-terminal hot-melt, common end insulation treatment, common end fixing), winding end final forming, and wire binding. [0003] Among them, the lead wire terminal of the motor winding refers to the part left outside the winding, including the winding wire head an...

Problems solved by technology

[0004] (1) The above-mentioned lead wire manufacturing process has become a bottleneck affecting the production efficiency of the motor, the production process is complicated, the efficiency is low, and the manufacturing cost is high;

[0005] (2) After the motor is manufactured, the motor windings need to be placed in a paint dipping furnace to dip and dry the windings. Often, after this process is completed, the lead wires will shrink due to paint dipping and drying, causing the length of the lead wires to shrink. At the same time, after the terminal on the side corresponding to the lead-out line is heated at a high temperature, the stress changes, resulting in poor manufacturability of the back-end assembly and poor electrical reliability
